CENTER-BEARING PLATE FOR CARS.

SPECIFICATION forming part of Letters Patent No. 440,335, dated November 11, 1890.

Application filed July 30,1890- Serial No. 360,392- (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES T. SoHoEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Center- Bearing Plates for Railway-Oars, of which the following is a full, clear, and exact description.

This invention relates to that class of center-bearing plates which are usually and by preference struck up in dies of plate-steel; or, in other words, the invention relates to pressedsteel center-bearing plates.

In the interchange of my pressed-steel center-bearing plates for the cast-iron and other center-bearing plates among the railroads of this country I have found it necessary to vary the form and construction in order to meet the requirements of the companies; but without specifying at this time wherein the present invention differs fromthe center-bearing plates heretofore patented to me I will proceed to set forth my invention, and finally particularly point out and claim the part or improvement constituting my said invention.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1' is a plan view. Fig. 2 is a central longitudinal section, and Fig. 3 is a central transverse section.

The body-plate a is made with a central cup I), which in turn is provided with a central reversely-turned frusto-conical tubular flange c. The truck-plate d is provided with a saucer-like cavity 6, elevated fromthe body of the plate and of complemental shape, and to receive the cup of the body-plate, and this saucer-like cavity is provided with a central upturned frusto-conical flange f, which fits loosely within the flange c of the body-plate. The plates at and d are provided with dowels g and h, respectively, for use in securing them to the body and truck timbers. These plates are of pressed steel or struck up in dies by preference. I prefer to employ, in connection with these plates, cast-metal filling-pieces i and j, respectively, which filling-pieces are made of skeleton form and fitted in the cavities formed by striking up the cup and saucer in the respective plates. The filling-piece 2' has the flange k, perforated centrally to form a bearing for the king-bolt, and is provided, also, with dowels Z to enter the body-bolster. The filling-piece j is provided with a centrally-perforated lug m to receive the king-bolt, and also to re-enforce the flange f. This filling-piece j is provided, also, with dowels nto enter the truck-bolster. These filling-pieces serve to prevent the plates from being crushed in use by affording bearings for their cup and saucer, respectively, which bearings extend to the base-line of the plates and come in contact with the portions to which they are attached. The filling-pieces maybe omit ted, however, and in such case the flanges c and f will be made of less diameter-that is to say, suflioient to take in the king-boltbut, as already indicated, I prefer to employ the filling-pieces.

The general outline of the skeleton fillingpieces is shown in Fig. 1, and the details of their form and construction are more fully shown in the other figures.

It will be observed that the filling-pieces are made to conform to the shape of the cup and saucer, respectively. The filling-piece 11 serves to re-enforce or brace the flange c,just as the perforated lug of the filling-piece jreenforces the flange f.

' The employment of the frusto conical fiangesc and f enables me to manufacture the plates more expeditiously and of greater strength than were these parts cylindrical, as has been proposed, and, moreover, the fitting and movement of parts are facilitated.

What I claim is- 1. Center-bearing plates for railway-cars, composed of a body-plate and a truck-plate struck up in dies from plate metal, preferably steel, of substantially uniform thickness throughout, the formerhaving a cup-likeprojection constructed with a central upturned frusto-conical flange and the latter having a saucer-like cavity, also provided with a central upturned frusto conical flange fitting loosely within the flange of the body-plate, the

cup and saucer being complemental one to the other, and in superficial contact, essentially, throughout their entire area, so as to afford extended bearings one for the other,

substantially as and for the purpose described.

metal inserted in the cup and saucer and forming bearings for the king-bolt, substantially as described.

4. Centerbearings for railway-cars, consistin g of abody-plate struck up from plate metal with a cup having a reversely-turned frustoconical flange, and a truck-plate also struck up from plate metal, and havinga saucer provided with an. upturned frusto-eonical flange, combined with a filling-piece for the bodyplate, having a flange constituting a bearing to the king-bolt, and also havinga portion reenforcing the flange of the cup, and a fillingpiece for the truck-plate, having a perforated lug re-enforcing the flange of the saucer and also forming a bearing for the king-bolt, substantially as described.

In testimony whereof I have hereunto set my hand this 29th day of July, A. D. 1890.

CHARLES T. SOHOEN.
